Srimad-Bhagavatam: Canto 10 - Chapter 1 - Verse 62

Sanskrit:

योऽस्मिन् स्‍नात्वा मदाक्रीडे देवादींस्तर्पयेज्जलै: ।उपोष्य मां स्मरन्नर्चेत् सर्वपापै: प्रमुच्यते ॥ ६२ ॥

ITRANS:

yo ’smin snātvā mad-ākrīḍedevādīṁs tarpayej jalaiḥupoṣya māṁ smarann arcetsarva-pāpaiḥ pramucyate

Translation:

If one bathes in this place of My pastimes and offers the water of this lake to the demigods and other worshipable personalities, or if one observes a fast and duly worships and remembers Me, he is sure to become free from all sinful reactions.

Purport:

According to the ācāryas, the Lord spoke this verse to make it clear to Kāliya that he could by no means remain in the Yamunā lake. Although the Lord had mercifully pardoned the serpent and ordered him to go to the ocean with all his associates, Kāliya should not even consider requesting to remain in the lake, because it was now to become a holy place for spiritual pilgrims.
